SNOW-PLOW.

Specification of Letters Patent.

Patented June 4, 1907.

Application filed November 28, 19%. Serial No. 345,474

To all whom it may concern:

Be it known that 1, PAUL HANNAGAN, a citizen of the United States, residing at Lawrence, in the county of Essex, State of Massachusetts, have invented a certain new and useful Im rovement in Snow Plows, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention comprises various improvements in the construction of snow-plows.

The general object of the invention is to produce a snowlow which shall be stronger and more dura lo, and at the same time lighter than in the case of plows heretofore designed for the same kinds of work.

Different features of the invention are adapted for general use and are applicable in the case of plows designed for various purposes in dealing with snow, mud, etc., although the invention in its more complete embodiment is an improvement in plows more especially designed for removing snow, mud, etc., from the gutters of streets.

In the drawings,-Figure 1 shows in perspective an embodiment of the invention in connection with a gutter snow-plow. Fig. 2 is a perspective showing the snowlow of Fig. 1 turned on one side thereof. *ig. 3 is a perspective view showing a framework of slightly modified construction.

Having reference more particularly to Figs. 1 and 2 of the drawings, at 4, 1, are shafts between which a horse may be hitched, at 5, 5, are side-beams extending from front to rear of the plow and mounted upon opposite sideportions of the frame presently to be described, the said side-beams supporting the floor 6 from which rise the stanchions 7, 7, etc, supporting the seat 8 for the driver. 9, 9, are braces extending from outer portions of the bottom of the seat 8 obliquely downward and inward to the floor 6, and shown as abutting against each other at their lower ends. Any other construction and arrangement of floor and seat and means of supporting the seat may be adopted in practice.

The frame comprises, in part, a plurality of cross-bars or cross-irons 10, 10, two in numher in the present drawings, as shown best in Figs. 2 and 3, although the number may be increased in practice if desired. Each of these cross-bars or cross-irons has its opposite end-portions provided with side-stanchions 10, 10*, the lower ends of these latter being bolted to the runners as presently I will be explained. Preferably, but not necessarily in all cases, the said side-stanchions are produced by bending down the end-portions of the cross-irons. Tothe cross-irons are applied the side-bars 11, 11. These sidebars are bolted, as at 12, 12, to the cross-irons. As thus secured together, the cross-irons 10, 10, and side-bars 11, 11, constitute the main elements of a frame which is rectangular in plan. For the purpose of preventing the frame from departing from such shape under the strain and accidents which areincident to its use, it is braced by horizontal ties or braces 13, 13, each thereof extending diagonally from one corner of the frame to an opposite corner, the ends of the said ties or braces being secured to the said corners by the bolts 12, 12, etc. The two ties or braces 13, 13, cross each other, and may be fastened together at the crossing-point by a bolt 14, Fig. 2, although the bolt may be omitted if desired, as indicated in Fig. 3.

Continuations 11 11 of the side-bars extend forwardly, downwardly, and then rearwardly, each of such continuations having an edge thereof presented in advance. The said continuations thereby are adapted to constitute noses or cutters by means of which the snow will be cut or parted in the forward movement of the plow. They are rounded vertically, and thereby are adapted to ride up over stones and unevennesses encountered extends rearward in continuation of the noses or cutter 11* at such side, the lower ends of the respective side-stanchions 10 10 being fastened to the respective runners by means of bolts 15, 15, etc. From the rear ends of the runners the side-irons extend upward to the side-bars 11, 11, forming rear stanchions 11, these latter inclining upwardly and forwardly. Preferably the side irons are formed each in one integral piece, although in some instances the respective portions 11, 11, 11 11", thereof may be constituted of separate pieces suitably bolted or otherwise fastened together.

termediate the side-stanchions 10 10*, at the respective sides of the plow, and each extending vertically from the corresponding side-bar 11 to the runner 11 below the same, each stanchion 11 having its lower end secured to the corresponding runner by a bolt 16, and its upper end bent transversely, see Figs. 2 and 3, and extended beneath the in their path. The runner 11 at each side" At 11 11, are side-stanchions located in- I runner and auxiliary runner.

middle portion of the length of the corresponding side-bar 11 and secured to the said side-bar by'a bolt 17, Fig. 3, passing vertically through the side-bar and the said lug.

Increased stability is secured by means of the dia onal braces or ties 18, 19, at each side of the frame, the pair of such braces or ties at a given side having the lower ends thereof secured by the bolt 1.6, while the upper portion of each forwardly-extending brace 18 is secured to the forward side-stanchion 10 and to the nose or cutter 11 by means of bolts 20, 20, Figs. 1 and 3, and the upper portion of the rearwardly-extending brace or tie 19 is secured to the rear side-stanchion 10 and rear stanchion 11 by bolts 21, 21.

The frame is stiffened transversely by bent braces 22, 22, of substantially Ushape, each of these latter having its middle portion secured by bolts 23, 23, etc., Figs. 2 and 3, to one of the cross-irons 10, 10, while its downwardly-extending diverging legs are engaged with the side-irons by opposite bolts 15, 15.

The described i jconstruction produces an openwork sled-frame which is very strong and possesses ample rigidity, and Which admits of readily being repaired in case necessity therefor should arise. I do not limit myself to employment of the same in the particular connection herein described, inasmuch as it is suitable for use in general.

Each runner is shown furnished with a shoe 24, 24,-having the ends thereof upturned to fit the rounded front and rear portions of the runner. I contemplate omitting or dispensing with the shoes in some instances. The manner of securing the same to the runners may be varied, although preferably I secure them in place as shown in the drawings, which latter represent each runner as having combined therewith an auxiliary runner-section 25 which is held in place by the bolts 15, 15, 16, and by means of other bolts 26, 26, the latter securing the upturned ends of the auxiliary runner to the nose or cutter 11 and to the lower portion of the rear stanchion 11, respectively. The shoe is secured in place by means of bolts 27, 27, etc., which latter are shown as having their heads engaged with the bottom of a shoe 24, and their stems passed up through the space between a runner and the corresponding auxiliary runner, with nuts applied to the thread ed upper portions of the stems of the said bolts and resting on the upper edge of the By tightening up the said nuts and bolts each shoe is securely clamped to the bottom edges of the corresponding runner and auxiliary runner.

I do not limit myself in all cases to providing the runner with an auxiliary runner and securing the shoe in place in the manner just described. I contemplate in many cases dispensing altogether with the shoes and allowing the lower surfaces of the runners themselves to rest upon the surface over which the plow is caused to pass.

At 29 is a draft-bar extending transversely across the front of the frame, with its opposite end-portions resting upon the forward portions of the diagonal braces of ties 18, 18 in the openings between the forward sidestanchions 10*, 10 and the noses or cutters 11 11 To the said draft-bar 29 the crossbar or cross-bars 30 of the shafts 4, 4, is or are connected loosely by shackles having attaching bolts 31, 31, which pass throu h the draft-bar 29. The end-portions of t e said draft-bar are held down upon the said portions of the braces or ties 18, 18, by means of metal straps 32, 32, passing over the said end-portions and having the extremities thereof secured by the bolts 20, 20, such straps also being secured to the draft-bar by the bolts 33, 33, shown in Fig. 2. Preferably, the outer sides of the side-iron which is intended to travel next to the curbing or edgestones of the gutter that is to be cleared, is closed or covered by a web 34, Figs. 1 and 2, of sheet iron or other suitable material, although I contemplate omitting this web or cover in many instances.

The mold-board 3 is provided with a facing 35, Figs. 1 and 2, that preferably is composed of sheet iron, boiler-iron having been used by me in practice, although other suitable material may be employed if preferred. The framework of the mold-board comprises the lower bar 36, Fig. 3, the upwardly-extending post 37 at the rear end of the said bar '36, and the forwardly extending upper portion or bar 38. Preferably, though not necessarily in all cases, the parts 36, 37, and 38, are formed in one piece or integral. They may be formed of separate pieces secured together in convenient manner. The forward extremity of the lower part 36 is bent upwardly to correspond with the lower portion of the nose or cutter 11 at the side of the plow at which the mold-board is located, and is secured to the said nose or cutter and to the corresponding portion of the corresponding auxiliary runner 25 by means of the bolt 26. The forward extremity of the up per portion 38 is secured by a bolt (not shown) to the draft-bar 29. If deemed advisable, the framework 36, 37, and 38 may be made continuous, with the front extremities of the upper and lower portions 38, 36, united by an intermediate or connecting portion. The upper portion 38 is secured to the rear cross-iron 10 by one of the bolts 23, which passes vertically through a transverselytwisted portion of the parts 38 shown in Fig. 3.

The framework of the moldboard is braced transversely to enable the same to withstand the lateral pressure between the same and the snow or mud which is being displaced, by means of braces 40, 41, 42, and

to the portion 38 of the framework of the mold-board by the bolt 45.

At 46 is a vertical stanchion having the upper extremity thereof made fast'to the upper portion 38 of the mold-board frame by means of the bolt 45, while the lower ex- .tremity thereof is made fast to the lower portion 36 by means of another bolt, not shown. Brace 43 has one extremity thereof bolted to the-intermediate stanchion 11 andthe other extremity thereof bolted to the stanchion 46..

Preferably, the rear extremity of the framework of the mold-board is raised a little relatively to the front portion to conform to the rise in the outer portion of a gutter, although in some instances I contemplate forming the mold-board with a horizontal under edge.

The lower bar 36 of the mold-board frame usually will be raised somewhat higher than the runners of the main frame, but in most cases the said lower bar will be sufficiently low to serve during the ordinary use of the snow plow as an intermediate runner.

Figs. 1 and 2 show the lower marginal portion of the facing of the mold-board bent transversely and extending under the mold-board frame to serve as a shoe, although this is not necessary in all cases. Brace is arranged at a different inclination in Fig. 3 from that of Figs. 1 and 2.

The plow may be made small and light enough to be manually operated.

One leg of the forward brace 22 passes through a hole in facing 35, as indicated in Figs. 1 and I do not limit myself to braces applied and arranged in the manner shown and described. in connection with the framework of the mold-board, and contemplate in some instances. constructing the plow to travel on wheels instead of the runners which are herein shown and described.
